Backup for mailboxes in Office365


One of our customers have migrated their mailboxes from Exchange 2013 to office 365.

He is asking: regarding the email backup for the IT side, how to backup mailboxes? is the only way is the pst file from the user side?

Any thoughts?

Thanks in advance.








Hi @ashwanit!


A suggestion is to look at Avepoint's solution - Cloud Backup Solution For Microsoft 365, Dynamics 365 And Salesforce | AvePoint


Avepoint got a great reputation and their new partner program is impressive!

From the technical point of view, backups can be divided into three types:

  • Full backup – a full backup creates a one-to-one copy of files. This type is the most sizable, but, at the same time, is the starting point for the two alternative kinds listed below.
  • Differential backup – copies data differences from the last full backup. It is a storage-friendly solution when compared to the full option.
  • Incremental backup – saves the changes which were applied since the last incremental backup cycle. This type is the quickest and the most storage-friendly. What is more, it can be performed in the real time.

If you add the archiving feature to a backup solution, it will provide you with a comprehensive tool which covers those two areas all at once. What is more, setting archiving and retention policies for storages lets you control the space consumed by your safe copies.

As of now, there is no backup feature in Office 365 so you will have to rely on third party backup tools.
